Passenger Lift Safety Parts Hydraulic Buffer For Elevator Lift
Parts
The hydraulic oil buffer is a critical safety device installed at the bottom of elevator
pits to absorb kinetic energy and provide a controlled deceleration
for descending elevator cars or counterweights in emergency
situations. It serves as the last line of defense to prevent
structural damage and passenger injury in case of over-speed or
free-fall conditions.
Working Principle
When an elevator car or counterweight exceeds normal operating
speeds, the buffer's piston compresses hydraulic oil through precisely calibrated orifices,
converting kinetic energy into heat. This gradual resistance
ensures a smooth, non-jerking stop while minimizing impact forces.
Most hydraulic buffers are self-resetting, allowing automatic return to standby position after activation.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
